How much longer should I let it go?

This may sound like a cheeky answer, but...till it's ready

At 1.5 kspp you are past what I usually render to, but with the reflective surface you may need quite a bit more. Only you can decide when it is "finished" .

Also, I didn't notice but as Bobvan pointed out you are using a kinda old version of Luxrender. Version 1.0RC4 is out on the luxrender download page now

Nice render overall, I like bots.

thats what I downloaded and I am pointing reality to the folder but 0.8 still shows up
